Three zinc(II) coordination polymers {[Zn(btp)(1,2-bdc)(H2O)]?·?H2O} n (1), {[Zn(btp)(1,3-bdc)(H2O)]?·?1.5H2O} n (2), and {[Zn(btp)(NO2-1,3-bdc)(H2O)]?·?2H2O} n (3) were synthesized by 1,3-bis(1,2,4-triazol-1-yl)propane (btp) and bis-carboxylate. Compound 1 is a thick 2-D network; 2 and 3 are undulated 2-D (4,4) networks. In 2 and 3, two adjacent networks interpenetrate to form a new 2-D double-layer network, which is sustained by hydrogen-bonding interactions. Compounds 1 and 2 reveal blue emission maximum at 351 and 403, respectively, in the solid state at room temperature. 相似文献

Three pillared polymeric complexes, {[Ni2(AIP)2(4,4′-bpt)(H2O)2]·4H2O}n (1), {[Co(AIP)(3,3′-bpt)]·H2O}n (2), and {[Ni(AIP)(3,3′-bpt)]·H2O}n (3) (H2AIP = 5-aminoisophthalic, 4,4′-bpt = 1H-3,5–bis(4-pyridyl)-1,2,4-triazole and 3,3′-bpt = 1H-3,5-bis(3-pyridyl)-1,2,4-triazole), have been hydrothermally synthesized and characterized by X-ray diffraction analysis. Both 1 and 3 have 2-D (6,3) honeycomb layers, which are further interlinked by bent pillared triazole-bipyridine ligands to form a bilayer structure. The structures can be simpli?ed to a (3,4)- and (3,5)-connected geometrical topology, respectively. Compound 2 has a Co-AIP layer structure in which the layers are pillared by 3,3′-bpt spacers to form the 3-D CsCl net. 相似文献

Three coordination polymers {[Mn(bte)(NO2-1,3-bdc)(H2O)]·H2O}n (1), {[Mn(btp)(NO2-1,3-bdc)(H2O)]·2H2O}n (2), and {[Mn(btb)(NO2-1,3-bdc)(H2O)]·H2O}n (3) (bte, 1,2-bis(1,2,4-triazol-1-yl)ethane; btp, 1,3-bis(1,2,4-triazol-1-yl)propane; btb, 1,4-bis(1,2,4-triazol-1-yl)butane, NO2-1,3- H2bdc, 5-nitroisophthalic acid) were synthesized by combination of bte, btp, and btb, conformationally flexible ligands with different spacer lengths, and the rigid [NO2-1,3-bdc]2?. In 1, two [NO2-1,3-bdc]2? anions link adjacent [Mn2(bte)2] rings to give an independent, 1-D metal–organic nanotube (MONT). The structure of 2 is an undulating 2-D (4,4) network. In 3, the combination of a [Mn(btb)]n single helical chain and two [Mn(NO2-1,3-bdc)]n linear chains assemble an intriguing independent, 1-D MONT. An interesting structural feature of 1 and 3 is that the nitro groups of each 1-D MONT interpenetrate into two adjacent 1-D MONTs to form a 1-D → 2-D interdigitated array. 3-D architectures in 1 and 3 are assembled via hydrogen bond interactions. The luminescent properties and thermal stabilities of 1, 2, and 3 were investigated. 相似文献

Compounds 1 and 3 are 4-connected 2-D networks with (44·62) topology. Compound 2 is a 1-D chain, while 4 features a 1-D ladder. These 1-D and 2-D complexes are further connected by hydrogen bonds to form 3-D supramolecular architectures. Complexes 1–4 showed very strong yellow luminescence emission. 相似文献

Three complexes based on fluconazole, namely, {[Co2(HFlu)(dpa)2(H2O)2]·H2O}n (1), {[Zn(HFlu)(IPA)]·H2O}n (2), and {[Mn(HFlu)2(IPA)(H2O)]·H2O}n (3) (HFlu?=?fluconazole, 2-(2,4-difluoro-phenyl)-1,3-bis(1,2,4-triazol-1-yl)-propan-2-ol; H2dpa?=?diphenic acid; H2IPA?=?isophthalic acid) have been synthesized. Single-crystal X-ray analysis revealed that 1 is a 2-D-network framework containing a trinuclear Co(II) unit, 2 is a 3-D framework, and 3 is 1-D double chain structure with a Mn2 metallocyclic core. The complexes have also been characterized by elemental analyses, IR, UV/vis and fluorescence spectroscopy, and thermal gravimetry. The phase purity of these polymers has been confirmed via powder X-ray diffraction. 相似文献

Compound 1 is a 3-D network with CdSO4 topology. Compound 2 contains 1-D ladder structures, which are interconnected by classical hydrogen-bonding interactions (O–H?···?O) to lead to 3-D supramolecular architectures. Luminescence was performed on 1 and 2, both of which showed strong fluorescent emissions in the solid state at room temperature. 相似文献

A tetrazole-based Zn(II) coordination polymer, [Zn(TMPT)2] n (1) (TMPT?=?5-(4-((1H-1,2,4-triazol-1-yl)methyl)phenyl)-2H-tetrazole), was synthesized by in situ reaction of 4-((1H-1,2,4-triazol-1-yl)methyl)benzonitrile, Zn(NO3)2?·?6H2O, and NaN3 under hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction. Complex 1 contains π–π stacking interactions between tetrazole rings and phenyl rings of the 2-D ordered layered structural framework, which contribute to the dielectric response. In addition, 1 was demonstrated to display strong blue fluorescence emissions in the solid state at room temperature. 相似文献

Two pairs of isostructural transition metal coordination polymers, {[Co(L)(H2O)]n} (1) and {[Zn(L)(H2O)]n} (3), {[Co(L)(4,4′-bipy)(H2O)]·H2O}n (2) and {[Zn(L)(4,4′-bipy)(H2O)]·H2O}n (4) (H2L = N-pyrazinesulfonyl-glycine acid and 4,4′-bipy = 4,4′-bipyridine), have been synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental and thermogravimetric analyses. The structures show that 1 and 3 display 2-D polymeric grid frameworks with a 3-connected (4, 82) topology. 2 and 4 also exhibit a 2-D polymeric grid structure, but are constructed by a 4-connected (4, 4) topology. The adjacent 2-D polymeric grid frameworks for 1–4 are further linked by hydrogen bonding O–H?O interactions to form 3-D supramolecular interweaved orderly networks. The fluorescent properties of 3 and 4 were investigated in the solid state. 相似文献

Three new complexes, {[Cu3(2,3-pyma)2(sip)2(H2O)5]·5H2O} n , {[Zn(H-2,3-pyma)(sip)(H2O)]·H2O} n , and {[Cd(H-2,3-pyma)(sip)(H2O)]·H2O} n (2,3-pyma = (2-pyridylmethyl,3-pyridylmethyl)amine and H3sip = 5-sulfoisophthalic acid) were synthesized and structurally characterized by single-crystal X-ray diffraction. The Cu(II) complex crystallizes in neutral two-dimensional layers in which the Cu(II) centers are bridged by both the flexible 2,3-pyma and the rigid sip ligands. The Zn(II) and Cd(II) complexes contain neutral one-dimensional chains linked by the rigid sip anions, whereas the flexible H-2,3-pyma ions only act as terminal ligands. The Cu(II) complex shows weak antiferromagnetic interactions, while the Zn(II) and Cd(II) complexes exhibit fluorescent emissions in the solid state. 相似文献

Four metal(II) complexes with benzene-1,2,3-triyltris(oxy)triacetic acid (H3L), {[Co1.5(L)(H2O)6]·6H2O}n (1), {[Co1.5(L)(4,4′-bipy)1.5(H2O)4]·4H2O}n (2), {[Co(HL)(2,2′-bipy)(H2O)2]·1.5H2O}n (3), and {[Cu(HL)(phen)(H2O)2]·H2O}n (4) (4,4′-bipy = 4,4′-bipyridine; 2,2′-bipy = 2,2′-bipyridine; phen = phenanthroline), were prepared and structurally characterized.

Reaction of a ligand N-(3,5-di-2-pyrazinyl-4H-1,2,4-triazol-4-yl)-2-pyrazinecarboxamide (Hpztp) with CuSO4 and Cu(acac)2 (acac = acetylacetonate), respectively, yields two distinct CuII coordination polymers {[Cu3(pztp)2(SO4)2(H2O)2]·3H2O} n and {[Cu(pztp)(acac)]·0.5H2O} n . Both complexes have been structurally determined and also characterized by physicochemical and spectroscopic methods. The results reveal that by using different anions (SO4 2? versus acac?), the dimensionality (from 2D to 1D) of the resulting coordination architectures as well as conformations and binding fashions of the pztp ligand are significantly changed. That is to say, the selection of anions will play a key role in inducing the formation of the crystalline materials. The thermal stabilities of both complexes have also been explored and discussed. 相似文献

In this paper, three luminescent metal–organic frameworks, namely: [Zn(p-IPhHIDC)]n (1), {[Cd(p-IPhIDC)(H2O)]·CH3OH}n (2) and [Zn(p-TIPhHIDC)]n (3), bearing two novel substituted imidazole dicarboxylate ligands, 2-(p-N-imidazol-1-yl)-phenyl-1H-imidazole-4,5dicarboxylic acid (p-IPhH3IDC) and 2-p-(1H-1,2,4-triazol-1-yl)-phenyl-1H-imidazole-4,5dicarboxylic acid (p-TIPhH3IDC), have been prepared and characterised through infrared spectra, X-ray powder diffraction, elemental analyses, thermogravimetric analyses and single-crystal X-ray diffraction. Ignoring the free methanol molecule and coordinated water in 2, 1–3 are similar structures. Moreover, the luminescent properties of the MOFs have been explored. It was found that MOFs 1 and 2 show good luminescent sensing of Fe3+ in varying degrees, and 3 of K+. 相似文献

Two complexes formulated as {[Cd(btec)0.5(tmb)H2O]·4H2O}n (1) and {[Cd(H2btec)(tmb)(H2O)]·2H2O}n (2) (H4btec?=?1,2,4,5-benzenetetracarboxylic acid, tmb?=?2-((1H-1,2,4-triazol-1-yl)methyl)-1H-benzimidazole) have been synthesized and characterized by elemental analysis, IR, and single crystal X-ray diffraction. Single crystal X-ray diffraction shows that 1 has a 2-D layer structure in which tmb bridges and all of the carboxylates from 1,2,4,5-benzenetetracarboxylate chelate. In 2 Cd(II) ions are bridged by monodentate carboxylates leading to a 2-D layer structure with all tmb ligands coordinated monodentate to Cd(II), hanging at two sides of the layers. Complexes 1 and 2 are further extended to 3-D supramolecular structures by hydrogen bonding interactions. Luminescent properties have been investigated in the solid state at room temperature. 相似文献

In the title compound, {[Zn(C8H4O5)(C12H8N2)]·H2O}n or {[Zn(OH‐BDC)(phen)]·H2O}n (where OH‐H2BDC is 5‐hydroxyisophthalic acid and phen is 1,10‐phenanthroline), the Zn atoms are coordinated by two N atoms from the phen ligands and by four O atoms from hydroxyisophthalate ligands in a highly distorted octahedral geometry, with Zn—O distances in the range 2.042 (4)–2.085 (5) Å and Zn—N distances of 2.133 (5) and 2.137 (5) Å. The {[Zn(OH‐BDC)(phen)]·H2O}n infinite zigzag polymer forms a helical chain of [Zn2(OH‐BDC)2]n units. Face‐to‐face π–π interactions (3.60–3.75 Å) occur between two phen rings belonging to the same helical chain. Consolidation of the packing structure is achieved by O—H⋯O hydrogen‐bonding interactions between the carboxylate O atoms, the hydroxyl group and the water molecule, forming two‐dimensional sheets. 相似文献

Reactions of the aromatase inhibitor letrozole derivative 4,4'-(1H-1,2,4-triazol-1-yl)methylene-bis(benzonic acid) (H2tzmb) with ZnII, CdII, or PbII salts under similar conditions resulted in the generation of three coordination polymers, namely, {[Zn(tzmb)(H2tzmb)] · H2O}n ( 1 ), [Cd(tzmb)(H2O)2]n ( 2 ), and {[Pb(tzmb)(H2O)] · DMF}n ( 3 ), respectively. Their structures were determined by single-crystal X-ray diffraction analyses and further characterized by elemental analysis, IR spectroscopy, powder X-ray diffraction, and thermogravimetric analyses. Complex 1 features a twofold 2D → 2D interpenetrated network based on corrugated 63- hcb layers, and complex 2 exhibits a flat 2D 4.82- fes network, whereas complex 3 presents a 3D hex net based on infinite rod-shaped secondary building units. The remarkable structural diversity may illustrate the powerful effect of metal ions on coordination assemblies. The spectroscopic, thermal, and photoluminescent properties of complexes 1 – 3 were investigated. In addition, the catalytic activity of 1 in the solvent-free ring-opening polymerization of ε-caprolactone was also discussed. 相似文献

Two CPs display 1D zigzag chain and linear chain structures, respectively. Furthermore, these 1D chains are extended into 2D supramolecular networks through hydrogen bonding interactions. The luminescence properties and photocatalytic behaviors of both CPs are reported. 相似文献
